r a 40mins. (01 36- 76) M similar reference characters designate corre-This invention appertains to footwear, and more particularly to shoes,which are adapted to' be worn by nurses and other personswhose callingnecessitates their being on their feet on greater part of their working]'101 1: :5 'v It has been proposed to provide a wedge-shaped pad ofcushion material (such as sponge orother rubber) in the-sole of the'shoeat theheel to arches' of the wearer. Suchshoes are admirable for thepurpose intended, 'but' the same are'open to certain objections, such asundue wear 'onthe heel face and the difficulty contingent'with therepair of the shoes when such wear occurs.-

It i's, therefore,one of the salient objects of my invention to providea shoe of the above character so formed as' to receive a rubberwear'lift or heel which can be readily replaced when worn.

Another important object of my invention is to provide a shoe having arubber cushioned pad at its heel provided with an offset in its lowerface to receive a removable wear heel lift, the offset portionpermitting the wear heel lift to extend flush with'and from acontinuation of the bottom of the shoe sole.

A further object of my invention is the provision of novel means forforming the heel seat in the heel cushion for receiving the replaceablewear heel lift, and novel means for reenforcing and strengthening theseat.

A still further object of my invention is to provide a shoe of the abovecharacter, which will be durable and efllcient in use, one that will besimple and easy to manufacture, and one which can be placed upon themarket at a reasonable cost.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described, claimed, and illustrated in theaccompanying drawing, in which:

Figure 1 is a fragmentary side elevation of a shoe constructed inaccordance with my invention;

Figure 2 is a fragmentary longitudinal section through the improvedshoe;

Figure 3 is a fragmentary bottom plan view of the improved shoe withparts thereof broken away and in section to illustrate structuraldetails;

Figure 4 is a. detail section illustrating a modified form of myinvention.

Referring to the drawing in detail, wherein sole l terminates at theheel of :theshoe, for a purpose which will be laterset forth. a 1:

Interposed between the insole 5 andthe wear sole 1 is a cushion pad8,which can beforiiied of sponge or anyotherzdesired type of rubber; Asclearly shown in Figure 2 of .the drawing, the

cushion-pad 8 extends beyond the wear sole"! and covers the entire areaof the heel; Thepad also extends over .the archof'ashoe to form aresilient support for the archof the wearer. If preferred, the cushionpad can have its sides covered by flexible leatheror fabric 9, which caneither be secured inplace by theuse of an adhesive'or bystitching; i

In accordance with my invention, the cushion pad 8 at the heel has itslower face oflfset as at 10 to provide a cavity or seat for a removableheel or wear lift II. This lift or wear heel ll can be formed fromrubber, if so desired. The lower face of the cavity or heel seat hassecured thereto a sheet of fabric or leather l2 which is firmly securedto the cushion pad by glue or other desired type of adhesive.

In order to form an adequate support for the rubber wear heel II a thinmetallic plate I3 is provided. This plate l3 covers substantially theentire surface of the heel seat and the forward edge thereof has formedthereon an offset forwardly directed sharpened, pointed penetratingprong l4. This prong I4 is inserted directly in the cushion pad 8 at thearch, and the plate itself is connected with the sheet of fabric orleather I2 by rivets or in any other preferred manner.

The wear heel H can take the form of an ordinary rubber heel and thesame is placed in the cavity or heel seat with its forward edge inabutting relation to the front wall of the cavity or seat formed in thecushion, and with the rear edge of the wear sole 1. Suitable fasteningelements, such as nails l5, are utilized for holding the rubber-heel inplace. These nails l5 are driven through the heel and through the plateI; and sheet l2 into the cushion. Obviously, when wear takes place onthe heel l I, the same can be easily removed, and a new heel placed inposition.

The wear heel or lift l I can be secured in place i These prongs haveformed thereonoppositelydirected heads II. The metallic plate ll, atspaced points, can be provided with openings or sockets I! for receivingthe headed prongs. In

this form of the invention, the heads I8 of the prongs H are firstinserted in the openings in the plate If, after which the rear end ofthe heel is swung upwardly, and the heads of the rear prongs are snappedinto the openings. To facilitate the insertion of'the rear prongs, thefaces thereof can be bevelled or bent on an angle, as indicated by thereference. character 20; When the heel becomes worn, it is merelynecessary to utilize an instrument to force "the heads oftherearmost'prongs out of the uppermost.

Changes in details may be made withoutdeparting from the scope of myinvention, but what I claim as new is: v v

' l'. A shoe comprising an uppenan insole, and an outsole, a padof-cushioned material interposed between the insole and the outsole atthe heel and arch of the shoe, the'wear sole terminating in rear ofthearch-and in front of the an outsole, a pad of cushioned materialinterposed between the insole and the outsole at the heel and arch ofthe shoe, the wear sole terminating in rear of the arch and in front ofthe heel, the cushion pad having its lower face oi!- set at the heel,and a removable wear heel secured in said offset, the lower face of thewear heel being flush with and forming a continuation of the outer faceof the outer sole.

3. A shoe comprising an upper, an insole, an outsole, said outsoleterminating at the rear part of the arch and in font of the heel, a padof cushioning material covering the heel portion of the insole andinterposed between the insole and the outer sole at the arch of theshoe, the heel portion of the cushion pad having its lower face providedwith, an offset, a strengthening plate secured .to the lower face of theoifset of the cushion pad and having its forward edge pro-- vided with aforwardly directed offset tongue anchored in the arch of the cushion, aremovable wear heel fitted in the offset of the cushion pad against theplate, and fastening elements extending, through the wear heel, throughthe plate, and into the cushioning pad, the lower face of the wear heelbeing flush with the lower face ofthe. sole.

4, A shoe comprising an upper, an insole, an outsole, a pad ofcushioning material interposed between the insole and the outsole at theheel and arch of the shoe, the wear sole terminating in rear of thearch, and in front of the heel, a strengthening plate secured to thelower face of the cushioning-pad having sockets therein, a removablewear heel, and a plate embedded in said wear heel, and resilientheadedprongsv on the plate extending beyond the upper face of the heelreceived in said sockets.
